Erase and Programming Performance
Notes
1. PA = program address, PD = program data, DQ7# = complement of the data written to the device, D
2. Figure indicates the last two bus cycles of command sequence.
3. Word mode address used as an example.
Notes
1. Typical program and erase times assume the following conditions: 25
2. Under worst case conditions of 90°C, V
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes program faster
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See
6. The device has a guaranteed minimum erase and program cycle endurance of 1,000,000 cycles.
